Look forward to our new Triple Decker and newly released Commercial Systems

Mountain Air Activated Carbon Filters remove 99% of everything under 20 microns from the air in one pass. This includes all organic odors. Some of the uses of these superior air cleaners are: food processing, indoor growing, restaurants, mortuaries, or anywhere odors and air quality are an issue. Effective up to 36 months, 2 to 3 times longer than other filters. Removes ALL organic odors. Don’t forget to filter your incoming air with Mountain Air Activated Carbon Filters. They will remove most incoming mold spores as well.

FILTERS NOW COME WITH TWO (2) DUST COVERS – WHICH WILL LAST FOR THE 3 YEAR LIFE OF THE FILTER.

* Indicative CFM: These air flows are indicative of the 37 month filter testing program at the end of which time the tested filters were still 100% effective. We have also found the tested CFM to be the most economical area in which to run the filters. EI: less electrical usage, fan wear, air noise, etc.

** The filters can handle considerably more air than the Recommended high CFM’s represent, however there are trade offs when running any air handling systems at high air pressures. There is a point where it is more economical to go up to the next size filter and this is what the maximum recommended CFM represents. For example, you could run a 400 CFM fan on a MA0620 filter, however it would be more economical to run a 400 CFM fan on an MA0820 filter. Although a larger filter may cost a little more, the savings in electrical usage, air noise, fan wear, etc. is a great trade off. Over the life of the system the additional cost will pay for itself many times over.

MountainAir Carbon is derived from sub-bituminous black coal deposited in a Pre-Cambrian formation deep within the Collie Basin over 230 million years ago. Thus, it is the planets oldest coal. Don't be fooled by claims that other carbon is any older as this would predate the carboniferous period. MountainAir carbon also has an extremely low ash content and trace element discrimination demonstrates it to be physically and chemically unique.

This feedstock is steam activated in the presence of large concentrations of particular gases that affect the activation process in a certain way. The result is an irregularly shaped activated carbon granule, unlike any other carbon on earth, predominated by mesopores in a physical distribution which is absolutely ideal for adsorption of volatile organic compounds as well as other associated odorous particles. MountainAir carbon displays a property known as decarboxylation where it strips carboxyl groups away from larger VOC prior to absorption. In effect, the carbon acts as its own pre-filter. NO OTHER CARBON IN THE WORLD (we have real time tested eight other carbon types) IS KNOWN TO DECARBOXYLATE. This property partly explains why MountainAir filters are the longest lasting filter on the market-3 years +.

MountainAir carbon is so unique and effective that it will remove most VOC of less than 30 microns. This includes acetone and acetate compounds, alcohol compounds, animal odors, benzene compounds, cooking odors, diesel fumes, epoxy resin odors, glue odors, paint odors, pollens, some poisons, odor bearing smoke particles, and most welding fumes just to name a few. MountainAir filters are less efficient at removing large smoke particles, but are extremely efficient at preventing and/or minimizing smoke damage to fabrics, walls, etc.

There are other types of carbon, but none that are nearly as effective as MountainAir carbon. Coconut carbon is one type of carbon used in filters, however, its main purpose if for gold extraction. Many claim that coconut carbon tends to have a high iodine count because it is dominated by micropores, rendering it unsuitable for larger plant VOC particles. As a result, we have never heard of a coconut carbon lasting for more than 12 months in an intensive plant VOC application. There is also amalgamated black coal carbon such as RC-412 Carbon which is derived from a surface grade and is used mostly for gold extraction and water purification. Though this carbon is very effective in purifying water and extracting gold it is not very efficient with VOc. This carbon stipulates a massive 33% variation in density which is desirable in aqueous suspension (water purification), however it is not desirable in air filtration, as density expresses trade off between air flow and filter efficacy. Once again don't be fooled by other gimmicks and expected life spans - go with the best – MountainAir

Filter Design: Some filters provide a conical inner base claiming that this improves airflow, however; it does not. This conical base attempts to straighten the airflow which in turn slows the air. This causes the airflow mass to strike the side of the filter, with some air exiting and other air traveling further down before either restraining the filter wall or exiting through the carbon bed. For this reason it is not used in any other filter, including the automotive industry.

Some filters also use a foam ring or an air bypass system that expands as the carbon in the filter settles out over time to prevent any air from escaping the filter before going through the carbon bed. This would not be needed if the carbon was properly placed in the filter. For example, some manufacturers machine pack the carbon in the filter through vibration compaction. This causes the smaller carbon particles to fall to the bottom while the larger ones remain at the top. Though you get more carbon in the filter it is not evenly distributed and will therefore effect the life span of the filter. Also, the foam ring prevents you from being able to refill the filter which means more money spent than needed.

MountainAir filters do not have a foam ring for the simple reason that we use a proprietary compaction method which packs the maximum amount of carbon into the filter evenly. MountainAir Filters are also refillable and more efficient in air ventilation because of this simple step.

Other gimmicks to be aware of include wrapping the filter in plastic. The intended implication of this is that the carbon would otherwise absorb moisture from the air. However, this is not true. Unless the air is being forced through the carbon bed the carbon will not absorb any particles. At MountainAir we box our filters properly, but we decline to wrap them in plastic at it offers no benefit.
